Answer:
The expression for Area of rectangle is .
Step-by-step explanation:
Given:
A rectangle has a length that is 4 units longer than the width.
Let the width of the rectangle be 'x' Units.
Length of rectangle will be =
If the width is increased by 7 units.
New Width of the rectangle =
Also the length increased by 5 units,
New Length of rectangle will be =
We need to write an equivalent expression for area of the rectangle.
Area of rectangle is given by length times width.
framing in expression form we get;
Area of rectangle =
On Solving the equation we get;
Area of rectangle =
Hence the expression for Area of rectangle is .
